Now understand this, boy. You're about to get a big load of lube injected up your ass.
It's going to be cold. Sometimes the nurse is not so nice as to warm up the lube before injecting it.
But, I see that your cock has gone soft. So, start stroking it. Think about what it's going to be like when you're all lubed up and I'm fucking your ass with a dildo. I may even stick the dildo up my pussy before I start fucking you with it. Wouldn't that be nice?
Don't cum yet!
Are you ready for the lube?
